26-bit Wiegand Output
Place the ST5 jumper on 1
Structure and description of the code
Format 26-bit hexadecimal
The output format is 26-bit Wiegand (Signals: DATA1, DATA0 and CLOCK)
The frame is made of 26-bit and built as follow:
First parity: 1-bit – even parity for the first 12-bit
Code of the badge: 6 half byte represent the last 6 digit of the code (4bit = 1 digit of a code)
Each byte is transferred from bit 7 to bit 0.
Second parity: 1-bit – odd parity for the last 12-bit

30-bit Wiegand Output
Put the ST5 jumper on 2
Structure and description of the code
The output format from the proximity reader is 30-bit wiegand (Signal: DATA1 and DATA0) and is
structured as follow:
Signals output in open collectors with pull up in
30-bit hexadecimal format.
First parity : 1 bit – even parity for the first 14-bit
Code : A code is formed from 7 half byte.
Each byte is transferred from bit 7 to bit 0.
Second parity: 1 bit – odd parity for the last 14-bit

44- bit Wiegand Format Output
Put the ST5 jumper on 3
Structure and description of the code
44-bit hexadecimal format
The output format from the proximity reader is 44-bit (Signal: DATA1, DATA0 and CLOCK) and is
structured as follow:
Data:

10 digit code number hexadecimal MSByte first
Each hexadecimal digit = 4 bit, MSBit first
LRC:
